【求助】Abaqus警告信息？ 20

各位行家，在abaqus提交计算之后出现了下述的warnings，有一些不是很理解，希望大神能够指点一下，谢谢！

问题1：warning如下，想问一下这是不是提示我需要把接触的主从面调换一下？

Please make sure that the mesh density of the slave surface in the contact pair (assembly_cobm18_block,assembly_block_combm18) is finer than the master surface. The analysis may run slower, may yield inaccurate results, and may require more memory if this is not the case.

问题2：warning如下，但不理解是什么意思？

The ratio of the maximum incremental adjustment to the average characteristic length is 1.11808e-02 at node 104206 instance part-1-1 on the surface pair (assembly_cobm24_block,assembly_block_combm24).

问题3：warning如下，根据字面意思的理解是有62个节点被调整超过一次，就有可能导致这些节点不在主面上。这62个节点所在的一对接触面我是既设了容差又设了过盈量，会不会是这个原因？

62 nodes have been adjusted more than once. The subsequent adjustments may cause these nodes not to lie on their master surface. The nodes have been identified in node set WarnNodeAdjust.
